GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent No. 593,894, dated November 16, 1897.

VApplication filed April 7, 1897. Serial No. 631,184. (No model.) i

To all whom t may concern;

Beit known that I, WILLIAM B. HUGHES, a citizen of the United States, residingin Philadelphia, Pennsylvania, have invented certain Improvements in Gas-Producers, of which the following is a specification.

My invention consists of certain improvements in the gas-producer for which I filed application for Letters Patent on the 27th day of November, 1896, Serial No. 613,600, one object ofmy present invention being to combine the producer-body and the mechanical pokers of theforrner apparatus with a fuelfeeding devicehaving as an element a reservoir into which the fuel is fed and in which it is maintained for a time before entering the body of the producer. I

A further object of the invention is to provide forthe removal of the ashes from the producer more readily than in the producers now in use, a still further object being toprovide a more acceptable method of supporting and driving the rotating producer-body than that shown in my former application, and a final object being to so mount the pokers as to prevent the escape of gas at the bearings, to provide efficient means of cooling the bearings, as well as the poker itself, and to permit ready access to the poker-head and its bearings without arresting the movement of the poker.

These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which-f Figure l is a vertical sectional view of a gas-producer constructed in accordance with myinvention. Fig. 2 is a sectional plan view of part of the same on the line x 0c, Fig. l, and on a larger'scale. Fig. 3 is an enlarged sectional view of the joint between the fixed and movable sections of the producer-body.

' Fig. 4: is an enlarged section of part of the of the producer.

4, which extends downsome distance into the combustion-chamber of the producer-body and also some distance above the top of the same, said magazine having at the top a fuel'- hopper 5, with counterbalanced bell-valve 6. Both the joint between the magazine-casing and the top of the producer-body and thatbetween the hopper-casing and the` top of the magazine are by preference water-sealed, so

-that while these parts are readily detachable one from another escape of gas at the joints will be prevented.v l

' The top plate of the producer-bodyhas bearings for the mechanically actuated pokers, whereby the agitation of the mass of fuel in the producerbody is effected, one of these bearings being shown in Figs. and 5, on reference to which it will'A be observed that the hollo'w poker '7 is secured to a head 9, which has opposite trunnions lO, adapted to bearings formed partly in the hollow boss ll, projecti ng upward from the top plate of the producer-body, and partly in acap l2, mounted upon and secured to said hollow boss, an opening 13 extending upwardly through this cap, so that the poker-head and its bearings are readily, accessible without removing the cap orinterfering with the operation of the poker, this openingbeing normally closed by a bell '14', the dependingsliange of which extends down into'a water-sealed chamber 15, surrounding said opening 13 of the cap, so that in the ordinary operation of the apparatus the escape of gas from the poker-bearing is effectually prevented.

Secured to the projecting end of one of the trunnions l0 of the poker-head is an arm 1G, the pin of which is connected by a rod 17 to a crank-pin on a disk 19, rotation of the latter thereforev imparting rocking movement to the poker. The poker-head and one of its trunnions lO contain a chamber' 20, communieating at the outer end with a water-inlet vpipe 2l and at the inner end with a pipe 22,

which extends down through the hollow poker 7 and discharges at the inner end or point of the same.

The upper end of the hollow poker communicates with a chamber 23, formed in the poker-head and in the other trunnion 10 of the same, and the outer end -of this chamber IOO discharges through a bent pipe 24 into the water-chamber formed on the top of the producer-bod y for the purpose of cooling the same.

The fixed upper section of the producerbody has at the lower edge an annular channel-bar 25,the depending inner flange of which is comparatively close to the depending inner fiange ot' an annular channel-bar 26, secured to the upper edge of the lower rotating section 27 of the producer-bod y, as shown in Fig. 3, so as to prevent coal from working outward into the joint between the two plates 25 and 26 and thereby interfering with the free ro tation of the lower section 27 of the producer. Around the upper portion of said lower section 27 of the produccr-bodyis formed an annular water-chamber 2f), into which depends an annular flange 30 on the fixed upper section l, so as to provide a water seal and prevent the escape of gas at the joint between the two sections of the producer.

The rota-table lower section 27 of the producer-body has an inverted frusto-conical ash-hopper 3l, with horizontal hearth-plate and lateral ash discharge openings 33, closed by swinging doors 34, and below and outwardly beyond the hearth-plate 32 is an ash-receiving plate 35, onto which the ashes can be drawn from the hearth through any one of the openings 33 when the door which normally closes said opening has been raised, so that an attendant standing at one point can, as the ash-hopper and its hearth-plate are slowly rotated, draw out the ashes through the openings 33 as they successively come into position in front of" him, the ashes bein-g deposited upon the receiving-plate 35, from which they can be removed by a fixed scraper 36, whereby they are directed into a chute 37 and thence into an ash-car.

Beneath the ash-collecting plate is an annular rack 39, with which meshes a spurwheel 40 on a short upright shaft free to turn in a bearing on the hollow base-plate 41 of the structure, said spur-wheel meshing with a pinion ft2 at the lower end of a driving-shaft 43, whereby power is transmitted to the lower section of the producer-bodyto rotate the same.

On the base 4l is an annular track 44, and on the under side of the producer-body structure is an annular track 45, and between these two tracks are interposed rollers 46, mounted upon spindles projecting from an annular frame 7, whereby the proper support of the rotating section of the producerbody is provided without interfering with the free rotation of the same.

The hearth-plate has a central air-pipe 49 projecting up into the ash-hopper and having the usual slotted head through which the air escapes into the mass contained in said hopper, a continuation of this aiipipe de ending from the bottom of the producer-bo y structure, so as to enter a water seal contained in a chamber 5 0, surrounding the fixed lower section 5l of the air-pipe, the latter having a lateral branch 52, through which the air is blown,and said branch having another branch 53 for the introduction of steam.

A central pipe 54 passes up through the fixed and rotating sections of the air-pipe and has at the upper end lateral branches 55, passing out through said air-pipe a short distance above the hearth-plate 32, the lower end of this pipe 54 being swivelcd to a fixed pipe 56 at the base of the air-pipe, and said pipe 56 having a branch pipe 57, through which steam or water may be forced, so as to be projected in to the ashes and clinkers upon the hearth-plate in order to soften the same preparatory to their removal onto the ash-receiving plate 35.

In Fig. 6 I have illustrated a modification of my invention in which the lower revoluble section 27 of the producer-body has in place of the ash-receiving plate 35 (shown in Fig. l) a fianged plate or trough 6l, which serves not only to receive the ashes f rom the hopper, but also contains water t-o serve as a seal for said hopper, the said water-sealed trough 6l, however, rotating with the hopper in the same manner as the ash-receiving plate 35, so that the ashes can be drawn out into the same from the hopper by an attendant standing at a fixed point, thus obvia-ting the necessity of traveling around the producer, so as to remove the ashes from all parts of the hopper and overcoming an objection to producers heretofore made which have fixed hoppers.

The gas-outlet G2 is formed in the fixed upper section of the producer-body above the level of the fuel therein, there being a considerable space between said fuel and the top plate of the producer-body, owing to the projection of the magazine 4 down into the up* per portion of the producer.

If desired, the poker-carrying top of the producer-body may be the rotatable part, as fully set forth in my former application.

Having thus described my invention, I claim and desire to secure by Letters Patentl. The combination of a gas-producer having a body divided horizontally at a point above the level of the fuel therein, one part being revoluble in respect to the other, with a fuel-reservoir carried by the upper portion of the produeerbody and projecting down into the gas-chamber.

'2. The combination of a gas-producer having a body with lower revoluble section and upper fixed section divided horizontally at a point above the level of the fuel, with a fuel magazine or reservoir carried by said upper fixed section of the producer-body and projecting down into the same, substantially as specified.

3. The combination of the lower section of a gas-producer body, an upper section having a fuel reservoir or magazine projecting down into the producer-body, one of said sections heilig revoluble and the horizontal division between the sections being above-the ICO IIO

593,894 i i a level Aof the fuel, and pokers mounted upon the upper section of the producer-body, substantially as specied.

4. The combination of the producer-body comprising upper and lower sections, one of which is revoluble, with joint-rings having inner depending flanges whereby the access of coal to the horizontal portion of the joint is prevented, substantially as specified.

5. The combination of the cap-plate. of the body of a gas-producer with a hollow poker having trunnions adapted` to bearings in said cap-plate, one of said trunnions having a chamber communicating directly with the upper end of the poker and the other trunnion having a chamber communicating through a pipe with the inner end or point of the poker, substantially as specified.

6. The combination of a gas-producer body with a vibratable poker having trunnions adapted to bearings on the producer-body the top bearing-plate having an opening extending vertically therethrough, and a sealed bell for closing said opening, substantially as specified. y

7. A gas-prod ucer body having a revoluble ash-hopper and an ash-receiving plate revoluble therewith and adapted to receive the ashes as they are drawn from the hopper, substan-tially as specified.

8. A gas-producer having a revoluble body with depending ash-hopper and hearth-plate, and lateral openin gs above said hearth-plate,

with doors for closing said openings, substantially as specified.

9. The combination of a gas-producer having a revoluble ash-hopper and an ash-receiving plate extending outwardly beyond said hoppery and revolving therewith whereby it is adapted to receive the ashes as they are drawn from the hopper, substantially as specied.

10. The combination of a gas-producer having a revoluble ash-hopper, an ash-receiving plate revolving therewith and extending outwardly therefrom, and means for removing ashes from said plate as it rotates, substantially as specified.

ll. The combination of the ash-hopper of a gas-producer, an air-pipe projecting up into the same, and a pipe passing through said air-pipe and having a branch or branches serving to proj ect water or steam laterally into the lower portion of the ash-hopper directly above the hearth, substantially as specified.

12. The combination of the ash-hopper of a gas-producer, an air-pipe projecting up into the same and having a rotative movement, a pipe passing through said air-pipe and having branches carried thereby and serving to project water or steam laterally into the lower portion of the ash-hopper above the hearth, and a fixed supply-pipe having a stuffing-box connection with the pipe carried by the rot'ating air-pipe, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
